Eco-Friendly Cruise Ship Design Includes Vertical Farms, Solar Sails, and a "Plant Kingdom"

If you want to reduce the environmental impact of your next vacation, you could do better than boarding a cruise ship. Luxury liners consume tons of fuel and produce even more sewage that is often dumped directly into the ocean. But cruises don’t have to be disastrous for the Earth by design: As inhabitat reports, the newly-designed Ecoship aims to be the most eco-friendly cruise ship on the seas.

The futuristic vessel was envisioned by the firm Oliver Design for the Japanese humanitarian organization Peace Boat. For decades, Peace Boat has been spreading its message of global social change through “peace voyages” that sail around the world. The Ecoship will embody this mission by being kinder to the environment than conventional cruise ships. Ten photovoltaic solar sails extend from the deck like giant fins, collecting clean energy to supplement the hybrid engine. Retractable wind generators harvest energy as well.

According to Oliver Design, the Ecoship will produce 30 percent less carbon dioxide than modern cruise ships. The vessel’s electrical system has also been updated with both the solar sails and kinetic floors onboard providing power. The biggest change comes in the sewage operations: Both the waste and water will be fed through a closed loop, which means that whatever’s produced is filtered and recycled again and again.

As these features are working behind the scenes, passengers will get to see some Earth-friendly amenities up close. A “plant kingdom” that covers five decks will consume surplus waste, water, and carbon dioxide produced by the ship, while vertical farms will be used to grow vegetables for meals.

When the Ecoship sets sail in 2020, it will continue to spread awareness of the changing climate that inspired its design. Oliver Design writes on its webpage, “The organization [Peace Boat] wants the Ecoship to be a turning point for the shipping industry and a flagship for raising awareness on climate change. As well as hosting Peace Boat’s voyages throughout the world, the ship will be used to stage exhibitions on green technology at the 100 ports where it is expected to dock each year.” You can check out the concept art for the project in the video below.

How to Build an Igloo, According to a Canadian Film From 1949

Centuries before you started building snow forts in your backyard, the Inuit had mastered using snow as construction material. This 1949 video, produced by the National Film Board of Canada (and with narration that uses some outdated terminology), illustrates how exactly people native to the Arctic can erect warm, temporary homes using nothing but a knife and the snow beneath their feet. The artifact was spotted by The Kid Should See This.

The igloo (or iglu in Inuktitut) in this footage takes around 90 minutes to erect, but a similar structure can be built by a skilled person in as little as 40 minutes. To put together the shelter, the two men carve up firm, packed snow into blocks that are about 2 feet tall, 3 feet wide, and 4 inches thick.

After the first row of blocks is placed in a circle on the ground, the builder slices a section of the blocks to create a slope. Each row that's placed on this foundation will spiral upward, creating a shape in which the blocks support their own weight. By the time the keystone block is fitted into the top, the igloo is strong enough to support the weight of a man.

The final steps are carving a doorway out of the bottom of the structure and plugging up the cracks with additional snow from outside. Even on a frigid Arctic night, the temperature of a well-insulated igloo can reach 40 degrees above the temperature outside. And the warmer the igloo gets over time, the stronger it becomes: The heat from the Sun and the bodies of the inhabitants melt the outer layers of the blocks, and that water eventually freezes to ice, giving the home more insulation and structural integrity.

If you aren't ready to build an igloo, here are some less intimidating snow projects to tackle this winter.

Charge Your Gadgets Anywhere With This Pocket-Sized Folding Solar Panel

Portable power banks are great for charging your phone when you’re out and about all day, but even they need to be charged via an electrical outlet. There's only so much a power bank can do when you’re out hiking the Appalachian Trail or roughing it in the woods during a camping trip.

Enter the SolarCru—a lightweight, foldable solar panel now available on Kickstarter. It charges your phone and other electronic devices just by soaking up the sunshine. Strap it to your backpack or drape it over your tent to let the solar panel’s external battery charge during the day. Then, right before you go to bed, you can plug your electronic device into the panel's USB port to let it charge overnight.

It's capable of charging a tablet, GPS, speaker, headphones, camera, or other small wattage devices. “A built-in intelligent chip identifies each device plugged in and automatically adjusts the energy output to provide the right amount of power,” according to the SolarCru Kickstarter page.

A single panel is good “for small charging tasks,” according to the product page, but you can connect up to three panels together to nearly triple the electrical output. It takes roughly three hours and 45 minutes to charge a phone using a single panel, for instance, or about one hour if you’re using three panels at once. The amount of daylight time it takes to harvest enough energy for charging will depend on weather conditions, but it will still work on cloudy days, albeit more slowly.

The foldable panel weighs less than a pound and rolls up into a compact case that it can easily be tucked away in your backpack or jacket pocket. It’s also made from a scratch- and water-resistant material, so if you get rained out while camping, it won't destroy your only source of power.

You can pre-order a single SolarCru panel on Kickstarter for $34 (less than some power banks), or a pack of five for $145. Orders are scheduled to be delivered in March.
